Hi guys, it's "/me too" time here for ppc. My mpc5200 board is jumping out of the
window when running "./latency -t1", while "./latency -t2" works. No trace dump,
hard freeze or spontaneous reboot, at your option. OPT_NUCLEUS_DEBUG spits
nothing. No issue with the regular user-space test though.
x86 has no problem at all.
